Giant Asian Hornets are in several counties in Washington State. The USDA is doing everything possible to eradicate the few found there, and we have every reason to believe they will be successful.
What we are seeing now in Kentucky is the European hornet. The European hornet is about 2/3rd the size of the giant Asian Hornet. In the fall hornets and wasps may appear more plentiful and aggressive as they are preparing to winter. I have included a link to the information we have on the European and giant Asian hornet below.
